REPLACE ONLY WITH PART NUMBER SPECIFIED.
VOLTAGE (MEASURED WITH VOLTMETER) IS DC VOLTAGE. (NO INPUT SIGNAL)
ELECTROLYTIC CAPACITORS ARE IN uF/WV.
ALL CAPACITORS ARE IN pF/50WV UNLESS OTHERWISE NOTED.
EX) 030 3pF 330 33pF 331 330pF 333 0.033uF
ALL RESISTORS ARE IN OHMS 1/4WATTS UNLESS OTHERWISE NOTED.
THE THICK LINES ON PC BOARD ARE THE PRINTING SIDE OF THE PARTS.
EX) PRINTING SIDE

THE COMPONENTS IDENTIFIED BY MARK ARE CRITICAL FOR SAFETY.
REPLACE ONLY WITH PART NUMBER SPECIFIED.
VOLTAGE (MEASURED WITH VOLTMETER) IS DC VOLTAGE. (NO INPUT SIGNAL)
ELECTROLYTIC CAPACITORS ARE IN uF/WV.
ALL CAPACITORS ARE IN pF/50WV UNLESS OTHERWISE NOTED.
EX) 030 3pF 330 33pF 331 330pF 333 0.033uF
ALL RESISTORS ARE IN OHMS 1/4WATTS UNLESS OTHERWISE NOTED.
THE THICK LINES ON PC BOARD ARE THE PRINTING SIDE OF THE PARTS.
EX) PRINTING SIDE
CIRCUIT IS SUBJECT TO CHANGE FOR IMPROVEMENT.

HA12167FB/HA12169FB
Audio Signal Processor for Cassette Deck (Deck 1 Chip)
ADE-207-110B (Z)
3rd Edition
Description
HA12167FB/HA12169FB is silicon monolithic bipolar IC providing REC volume system, Level meter
system and Dolby noise reduction system* in one chip.
Functions
• REC equalizer × 2 channel
• Equalizer volume × 2 channel
• Dolby B/C NR × 2 channel
• REC/PB input electronic volume × 2 channel
• Level Meter × 2 channel
• DAC for adjusting bias × 2 channel
Features
• Available to create characteristics of REC equalizer by changing external resistor, no coil
• Equalizer volume is available to calibrate recording automatically with micro-controller
• Electronic volume built-in is available to set the level of recording and play back automatically with
micro-controller
• 4 types of input (3 out of 4 are by way of electronic volume)
• Input electronic control switching is irrelevant to REC/PB electronic control switching
• Dolby noise reduction system is available with double cassette decks (Unprocessed signal output
available from recording out terminals during PB mode)
• Log-compressed level meter output is range from 0 V to 5 V (Usable as music search switchable gain of
0 dB and 20 dB respectively)
• Normal-speed/high-speed, normal/metal/chrome fully electronic control switching built-in
• NR-ON/OFF, Dolby B/C, MPX ON/OFF fully electronic control switching built-in
• Reduction of the number of pins by transfered serial data to electronic volume control switching and
another control switching (Controllable from micro-controller directly)
• Small the number of external parts
